Abstract Kokowska-Pawłowska, M. and Nowak, J. 2013. Phosphorus minerals in tonstein; coal seam 405 at Sośnica- Makoszowy coal mine, Upper Silesia, southern Poland. Acta Geologica Polonica, 63 (2), 271-281. Warszawa. The paper presents results of research on tonstein, which constitutes an interburden in coal seam 405 at the Sośnica- Makoszowy coal mine, Makoszowy field (mining level 600 m), Upper Silesia, southern Poland. The mineral and chemical compositions of the tonstein differ from the typical compositions described earlier for tonsteins from Upper Silesia Coal Basin area. Additionally, minerals present in the tonsteins include kaolinite, quartz, kaolinitised biotite and feldspars. The presence of the phosphatic minerals apatite and goyazite has been recognized. The presence of gorceixite and crandallite is also possible. The contents of CaO (5.66 wt%) and P2O5 (6.2 wt%) are remarkably high. Analysis of selected trace elements demonstrated high contents of Sr (4937 ppm) and Ba (4300 ppm), related to the phosphatic minerals. On the basis of mineral composition the tonstein has been identified as a crystalline tonstein, transitional to a multiplied one.

Basin Area

In the Pestan River Basin, the right tributary of the Kolubara River, a complex degradation of natural conditions has been expressed over the decades. The exploitation of lignite in the Kolubara Coal Basin, which is in large part located in the territory of this basin, as well as accompanying activities related to it, are the dominant activities that lead to the degradation of soil and hydrological conditions. If other land use types are added to this, it can be concluded that the land cover in the studied territory suffered significant negative changes. The above mentioned activities have led to land loss and deterioration of its quality, and the regulation works due to dislocation of the Kolubara watercourse into the Pestan riverbed have caused numerous degradation of landscapes, reduced the basin area and shortened its watercourse, led to morphological changes of the river network and deterioration of the surface water quality. The aim of this paper is to perform a geospatial analysis of all areas in which the degradation of soil and hydrological conditions is present, in order to prevent their further degradation and proper management of these areas.
